The SOWU project responds to a request made by the Ministry of Water and Environment of Uganda to the Climate and Clean Air Coalition, a UNEP-convened initiative. Organic waste mismanagement is one of the most significant challenges for urban authorities in Uganda. Waste generation exceeds technical and financial capacities, while the country aims to reduce its net GHG emissions by 24.7% below business-as-usual levels by 2030. To curb the waste-related emissions, the SOWU project aims to devise a national roadmap for the mitigation of short-lived climate pollutants (SLCPs) and enhance the sustainability of the organic waste sector in Uganda. The overarching goals of the SOWU project are to improve organic waste management in Uganda, enhance the health of the general population, and valorise organic waste by promoting the deployment of bioenergy systems such as anaerobic digestion.
